Specification of Letters Patent. Patented prl,

Application led December 23, 1912. Serial No. 738.201. i

To all '1r/1.0m.l it may com-ern Be it known that I, lVALTnn'E. Vimonamn, a citizen of tlie United States, and a resident of the city of Chicago, county ot' Cook,

new and useful Improvements in Aeroplanes, ot' which the following is a specilication.

My' invention relates lto aeroplanes 'and particularly to mechanism for ,guiding and stabilizing the same.

The object of this improvement is to provide a simple and effective device whereby the planesI in which the propellers rotate will be tilted in accordance with the tilting of the stabilizing planes iii-order to facilitate the control of the aeroplane.

Other objects will appear hereinafter.

The invention .consists in the combinations and arrangements of parts lhereinafter described and claimed.

The invention will be best understood vby forming a part ot this specification, and in which, f

Figure 1 is a broken longitudinal section ot' an aeroplane embodying my invention, Fig. 2 is a section of the Same taken on line .1fnin Fig. 1 and looking in the direction of the arrows 2 2, Fig. 3 a similar view of the same taken on line .r-.r of Figi but looking in the direction of the arrows Figft is au enlarged detail View. in per- 'mounting Fig. 5 a ,rear elevationot the stabilizing and guiding planes, Fig. G is an enlarged vertical .section taken on line 6-6 in Fig. 1. Fig. T is an enlarged section taken on line T---T in Fig. Il. and Fig. S is an cnlarged fragmental section taken on line S-8 in Fig. 5.

The preferred t'orm of construction, asr illustrated in the accompanying drawings, comprises a central bean'rf) in .the top porlength thereof and a keel 10 connected with the front end of the beam `l and curved downwardlyt'or a distance, then'exteuding parallel with the beam 9 throughout the length of the aeroplane. A plurality of` posts 11 are secured between the beam 9 and keel 1U which with a plurality of tie wires 12 space the beam 9 and keel 10 rigidly apart'.

plurality of upwardly `curved ribs-lfspaced apart andr providedl with' a rail 14 at their outer ends to space these outer ends apart.

A plurality ot' tie wiresll connect tlielfkeel l() with ythe rails 14, 'as is clearly illustrated.

A .front wheel 17 is mounted in a suitable 4fork 18 and the latter is j'ournaled in suitable journals in the keel 10 to support the forward end of the aeroplane when `resting on thev ground. The fork 18 is provided with laterally extending arms 19 whiclrare connected 'by means ot' thecables Q0 to the..

steering mechanism of the aeroplane which fwill be described later. The rear endvof the aeroplane is Supported on a pair of rear wheels 2l mounted on a suitable axle 2Q which latter is Secured to the keel 10.'A The axle 22 is further secured to the keelI by means of brace wires Q3 as is fully illustrated in Figs. 1 and 2. y

Mounted in the forward part of the acrovvplane immediately over the front wheelll'f-ff is a post 24: which is provided with a slot-'K25 and secured on the sides of the post 24 are'angular shaped supports 2G whiehare provided with perforations registering with a perforation through the central portion oth.

the post 2J: to provide suitable bearings for a rotating shaft 27. lathe slot 25 onthe shaft 2T is secured a lever 28 to rotate with said shaft 27. 0n the ends of the shaft 27 extending through the brace members 26 are@ the aeroplane'is a perpendicularly disposed post 2li-,l with a slot 34 mounted in suitable hearings'in the beam 9 and keel 10. Fulerumed on a pivot 35 is a lever 36 in the slot 34 of the post for vertical swinging. v A

handle portion 37 is provided on the end of lever 36 and extended to-a convenient-.position near the operators seat 38 in the aeroplane. f

Extending laterally from the beam 9 is a Secured near the tops of the vertical post,`

Secured to the tops of the ribs 13 is a. conventional coveringr 15v ot' suitable fabric.Y

Rotatively mounted in the rear portion'fot'r;

ion

33 and post 24 are pulleys 39 over which those indicated to cause the machine, to decables 40 are passed. The end portions of the cables 40 are connected to suitable positions on levers 36 and 28 to e'll'ect simultaneous pivotal movemei'xt ol said levers.

The vertical post 33 extends through the keel 1U and is provided on its bottoni end with a lever 4l and said lever 41 is operatively connected with the arms 1.9. of the fork 18 to effect guiding of the. aeroplane when 'the saine is on the ground. A vertical post 42 is journaled in the rear end por tions of the beam 9 and keel 10 and is provided with a longitudinally extending slot in which is secured the rudder plane 43.

Near the lower end of said post 42 are. laterally extending arms 4-l'which are connected7 yby means of cables 45, to arms 4G formed on the lower end of the vertical post 33 to cause the shaft 42 to rotate simultaneously,7 with the shaft 53 to effect guidingr of the aeroplane.

Stabilizing planes 47 are mounted on a suitable slitted shat't 4S which is journalcd in a bearing through the post 4'2 and rudder plane 43 as is clearly shown in Figs. T and 8,. The construction is suoli, that the stabilizinar planes 47 will turn with the shat't 48.

' as indicated by the dotted lines in Fig. 1.

Pulleys 49 are mounted near the top and bottom portions of the post 42 and on the beam 9 and near the bottom of one ofthe posts 11. as clearly illustrated in Fig. 1.. Cables 50 are secured to the rear ends of the stabilizing planes 47 and passed over the pulleys 49 and connected vwith the lever 36 to effect tilting of the stabilizing;` planes 47 upon pivotal movement of the lever 3G on its pivotal point 45.

In operation, the aeroplane is placed in a suitable position to make flight and the engine started in the usual manner. The operator moves lever 3G on its pivotal point in the direction indicated by dotted lines Bo inl Fig. 1 to eilect tilting of the propeller-s 31 in the direction indicated by the dotted lines 31 in the same figure and the stabiliving planes 47 in the direction ot' the dotted lines shown in the same figure. to eiiect ascent of the aeroplane. It will be seen that when the propellers are inclined in the direction indicated they will exert an upward as well as a forward pull on the aeroplane and as soon as the aerlnilane begins to lift the tilting of the stabilizing planes 47. as indicated, will increase the angle of incidence of the lifting' planes which comprises4 the ribs 18. covering 15 and connecting portions. lnthis manner ascension may be made more quicklyY than with aeroplanes of conventional type. Then it is desired to descend the lever 36 is moved in the opposite direction than that indicated to effect tilting of the propellers 31 and the stabilizing planes t7 in opposite directions than -plained lVhile T have illustrated and described thiI preferred form ol construction l'or carl-yin;l my invention into effect this is capable ol' variation and modification without departiner from the spirit ot' the invention. l, therefore, do not Wish to be limited to the. precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the. appended claims.
